To all 'whom may concern:

Be it knownthat I, MAX Po'rzsoH, a citiy zen of the United States, anda residentof Ridgewood, in the county of Bergen and State of New Jersey, have invented a new and Improved Combined Finishing Machine for Pile Fabrics, of which the following is a full, clear, and exact description.

This invention relates to a combined finishing machine fori pilefabrics and has yfor'an object to produce a structure wherein the finishing orfpart of the finishing may be done in a more expeditiousmanner and at a 'minimum expense.

Another. object`lis to provide a particular form of pfile raising machine which may be adjusted readily to 'produce a pile raising operation to any desiredextent, Ythe structure being arranged to readily -act on the cloth while the cloth is passing from one machine -to another during theprocess of finishing. -v

A furthenobject of the invention is to provide a pile raising machine which is so connected up .with the power driving members that it may operate at its usual speed ordinarily but' may be quickly and easily drawn into extremely slow speed so that the 'cloth may have a continuous uninterruptedA 4movement at all times.

In the accompanying "drawings- Figure 1 is an'butline of several associated devices used in finishing pile fabric.

Figure 2 is an enlarged side view of the pile raising machine shown in Figure 1.

Figure @is a top plan view of the pile raising machine shown in Figure 2,'the upstanding bracket at the one end being ,brokenof l Figure-4.- is a fragmentary sectional view through Figure 3 approximately on line `Figure 5 is afragmentary sectional view through Figure -3' V approximately on line lower part of the structure shown in Figure 5, the same illustrating brakes for the Fi-'gare 6 a fragmentary side view of the re? is an enlarged -fragnn'antary sec-V uview through Figure .5 approximately process is thepassing of the cloth through a pile preparing machine and also through a )ile raising machine, after which it is act successively on a strip of fabric from the pile preparing to the drying operation inclusi ve. It will be noted from Figure 1 that the fabric is automatically fed from one machine to the other, and consequently,lthe linishling operationis uninterrupted. d

Referring to the accompanying drawings by numeral, 11 indicates pile `preparing machine which is provided with tanks 12 and 18. It'will be notedthat asthestrip of fabric leaves the pile preparing machine 11, it is squeezed by the respective squeezing rollers 14 arid passes over suitable guide rollers to a l guide roller l5 supported on the frame 16 of the pile raising machine 17. From roller l5 the strip of cloth passes' over suitable guide rollers 18 and 19 to a spreader 20 and from thence overa supporting roller 21. -From the roller 21 the cloth passes above Ithe pile rollers 22and below the tension rollers 23 to the driving roller 24. From the driv-- ing roller 24, the strip of fabric passes over a .sfireader 25 of any desired construction. an

from thence between the respective tension rollers 26 and pile rollers27 to a second driving roller 28. `From the driving roller 28, the fabric passes over guide rollers 29 toV 'the guide roller 15 ofthe next pile raising machine 17. From the pileV raising machine 17, the fabric passes over suitable guiding rollers to some generally known other finishing machine. It will thus be seen that when Vthe fabric passes through the various machilies indicated in Figure 1, it will 'be prepared, the pile will be raised' and the entire abric may readily pass through other finishing machines. e y

By the mechanism shown'in Figures 2 to 5 inclusive,means have been provided for ordinarily running the fabricr through the machine ata normal or high speed and whenever desired, to slow down the speed until it moves very slowly. In producing a. construction to carry out this idea and certain others, there are provided ldriving rollers 24.. and 28, drivingroller 24 being IOS i by the `opposite direction by the drive roller 28.

driven throughthe action of a sprocket 31, said sprocket being driven by a chain 32 passing over a sprocket 33, which sprocket is rigidly secured to the shaft 34. The shaft 34 is rigidly secured to a gear 35 meshing y continually with a pinion 36, said pinion being rigidly secured to the shaft 37. rlhe shaft 37 (Figure 3) has a clutch member 38 splined thereon operated by a suitable hand actuated lever 39. A high speed pulley 40 is rigidly secured to the shaft 37 by a key or other' suitable means and is designed to be driven by a belt, which belt may be shifted to the idler 41 or to the slow pulley 42. When the belt is operating pulley 41, no power is transmitted to the machine, and consequently, the machine stops. lf' it is shifted to the high speed pulley 40, the machine will operate at its maximum speed but when the belt is shifted to pulley 42, the machine will be operated but at an extremely slow speed. Sometimes slight repairs or adjustments are desired or may become necessary and by reasdn of the extremely slow speed under Whichthe machine is operating, t 1e desired repairs may be made.-

lt will be noted that the pulley 42 is keyed to a sleeve 43 and said sleeve is also rigidly keyed to a pinion 44 which pinion continuallymeshes with a large gear 45. rlhe gear 45 carries a stub shaft '46 to which 'the pinion 47 is rigidly secured, said last mentioned 48 rigi ly secured to the sleeve 49, which sleeve is loosely, mounted en the shaft 37 and which sleeve also is rigidly secured to the clutch member 50, said clutch member co-acting with the clutch member 38. When the power belt is shifted to the pulley 42, lever 39 is moved to bring the clutch members'38 and 50 into engagement whereupon shaft 37 will be driven very slowly and will permit movement of the machine for driving the same very slowly. After the desired repair or adjustment has been accomplished, 'the pulley may be shifted back Lto' the high speed pulley 40 and the lever 39 moves for disengaging the clutch members. Itwill be noted that the shaft 37 continues Ato rotate whether the high Speed pulley 40 is being driven or whether the slow speed pulley 42 is being driven. Power is transmitted from shaft 37 `through pinion 36 to the gear wheel 35 and from thence' to the shaft 34.' Power is not onlyv transmitted from sha-ft 34 through thechain32 and associated parts but also through, the respective gears 51 and 52 to the drive roller 28 whereby the cloth is pulled in one direction drive roller 24 and pulled in the Mounted on the frame 16 are a plurality of pile raising rollers 22 which are not driven but are permitted to rotate as the fabric is pulled thereover. TheA pulling of inion meshing with a gear wheel.

the fabric over these pile raising rollers will cause the pile to be raised to a great or less extent. To secure desirable results in pile raising, these rollers are prevented from freely rotating and, consequently, there will be a resistance to the rotary movement caused by the movement of thecloth over these rollers. This resistance is caused by providing a brake wheel 54 (Figures 5 and 6) secured to-each of the rollers. Each of the brake wheels .54 is provided with a brake band 55 secured at 56 to the frame of the machine while at 57 threaded tension member is provided whereby any desired braking tension maybe secured. In order to hold the strip of fabric against these pile raising rollers, a number of tension rollers 23 are provided, these tension rollers being preferably smooth rollers of any desired kind for holding the clutch against the pile raising rollers. The rollers 23 are peferably staggered in respect to the rollers 22. 4lt will be noted that the pile raising roller 22 will raise the pile as the cloth is pulled by the roller 24 but an independent set of rollers 27 is provided for raising the pile as the cloth is pulled by the roller 28. The rollers 27 are mounted on a vertically adjustable bar 60 and are provided with brakes:

61 similar to the brakes shown in Figures 5 and 6. This is true of all the rollers 27 except the roller 59 which is driven by a chain 62 passing over a sprocket wheel 63 and over a sprocket wheel 64 secured to the shaft of roller 24. One or more guiding pins 65 are provided at each end of the respective sup porting bars 60 for guiding the same in its up and down movement. Also, at each end of the respective bars 60 there is provided a tension screw 66 which is threaded into the bar and presses against an enlargement 67 on the frame 16 whereby the respective bars 60 may be raised and lowered as desired. Each of the tension screws 66 is provided with a notchedL wheel 68 adapted to be engaged by the spring pressed locking catch 69 for preventing accidental rotation thereof. In the accompanying drawings, four of these tension screws and4 guiding rods are shown though if desired a greater number could be used.

Co-acting with the pile lraising rollers 27 are tension rollers 26 similar to rollers 23 llbut acting on the upper run of cloth pul ed by roller 28. 'As indicated in Figure 4, the rollers 23 and 26 are mounted on the respective bars 71 and 72, there being two bars 71 and two ban 72, namel one bar of each kindV on cach side of t e machine. Each air of: bars is provided with a pair of racls 73 a nd 74 at each end, rack 73 being connected with the bar 72 While rack 74 is rigidly connected with bar 71. A pinion 75 is provided with each pair of rack bars and is positioned in mesh therewith at all times. A transverse shaft 76 is provided at each end of the machine and rigidly secured to the respective pinions 75.

' Each of the shafts 76 1s provided with a repairs on the worm gear 77 meshing with the respective worms 78 secured to the shaft 79. The shaft 79 is mounted on suitable brackets carried by the frame 16 and is designed to be operated manually by the hand wheel 80. When the hand wheel 80 is rotated in one direction, the bars 71 and 72 will move apart and when rotated in theopposite directio'nwill move towards eachother.

When these bars are positioned as shown in same, the slow driving mechanism is thrown into operation and, consequently, the parts will move" very slowly though the cloth will continue a `forward movement. After the repair or desiredA adjustment hasbeen 'Y secured, the high speed driving mechanism other is thrown into operation and the parts continue to function as above described. It

will be noted that the fabric starts from a suitable pile or supply and first passes,

through the pile preparing machine 11 and then immediately through the first pile raising machine 16. The cloth, as indicated in Figure 1, passes by a continuing movement from the first pile raising machine to a second andA from the second directly into finishing machines not subject to these claims.

What I claim is i 1. A pile raising machine of the character described,l comprising a plurality of pile raising rollers, said rollers beingv arranged in sets, one set of rollers being movable as a unit toward and from the other, means for adjusting and locking said set of rollers in different positions in res ect to the other set of rollers, means for orcing a strip of cloth through the machine so as tobe acted on by both sets of rollers, and spreading means for spreading cloth immediately before it approaches the respective set of rollers.

2. A pile raising machine of the character described, comprising an vupper and a lower set of pile raising rollers, means for propelling a stripof cloth so that it will pass all of said rollers and the same face will engage said rollers, an upper and lower set of tension rollers co-acting with the pile raising rollers, a supporting frame for each set of tension rollers, a plurality of racks carried byl said frames, the racks of one frame extending toward the racks on the opposite frame, a pinion arranged between and meshing with each air of rocks, a shaft carried by each set ci) pinions, a worm wheel mounted on each of said shafts, a worm meshing with each of said worm wheels, anda manually rotatable shaft connecting said worms sothat they will operate in unison whereby when said shaft is rotated in one direction said sup orting frames will be moved apart and when rotated in the opposite direction said supporting frames will be moved towards eaeh other. Y y

3. In a finishing machine of the character described, a pile raising apparatus, comprising upperand lower rows of pile raising rollers, means for pulling a strip of cloth in a horizontall plane past the upper row of said rollers, means for pulling said cloth in the opposite direction past the-lower row of rollers, and means movable toward and from the respective rows of rollers for holding the cloth in operative position in respect to said rollers.
